An interesting concept, but incredibly unforgiving. There's no way to tell where the big things are and you can only see a very small area. If touching a larger body didn't take you back to the start of the level after a lot of painstaking work this game might be fun, but as it is it's just an exercise in frustration.
neat idea but too easy.
also seeing as there's never a situation where you aren't helped by firing why bother making us click the mouse button. it should just autofire the whole time.
